Forces and motion
Speed (m/s)
- the distance travelled by an object in unit time
= 𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒 (𝑚) ÷ 𝑡𝑖𝑚𝑒 (𝑠)
Acceleration (m/s^2)
- the rate of change of an object’s velocity
= 𝑠𝑝𝑒𝑒𝑑 (𝑚/𝑠) ÷ 𝑡𝑖𝑚𝑒 (𝑠)
Scalar quantity Vector quantity
A ected by: Magnitude only Both magnitude and
direction
Example Mass, time, density, distance Displacement, force
Centripetal force - Related to the space and gravitational force
- When an object moves in a circle at constant speed, the direction is always changing.
- Velocity is not constant, producing the centripetal force towards the centre of the bent.
Mass Weight
Amount of matter in a body Gravitational force acting on a body
Kilogram (kg) Newton (N)
